AMORPHOUS ALLOY METAL CORE & RIBBON

 Amorphous magnetic metal used for transformer cores does give the possibility of decrease core losses compared to standard core steel materials. The magnetic core of this transformer is made with amorphous metal, which is easily magnetized / demagnetized. Amorphous metal is a unique alloy whose structure of metal atoms occurs in a random pattern as opposed to conventional Cold-Rolled Grain-Oriented (CRGO) silicon steel, which has an organized crystalline structure leads to higher resistance to magnetization and Amorphous metals are made of alloy which have no atomic order.

 A comparison between amorphous metal and CRGO steel in terms of properties is presented below.

 Amorphous Metal material allows the construction of a low-loss core. Amorphous metal is extremely thin, has high electrical resistivity, and has little or no magnetic domain definition. Cores made from this material can exhibit 60-70 percent lower core losses than one made of conventional steels.
